Key Features & Benefits at a Glance
- Exceptional corrosion resistance with black-oxide coating, extending service life in demanding industrial environments.
- Superior holding power and minimal loosening due to the Class 3A thread fit and UNF fine thread design.
- High-strength performance from alloy steel with Rockwell C45 hardness, ensuring reliable, long-term fastening.
- Easy installation and removal with the 1/8" hex drive, providing secure tool engagement in confined spaces.
- Precise component positioning enabled by the 90° cone point tip, which bites into surfaces for a firm, non-slip grip.
- Space-saving headless design ideal for applications where a flush or low-profile finish is required.
- Guaranteed compliance and reliability meeting ASME B18.3, ASTM F912, RoHS 3, and REACH standards for safe, industrial use.
Professional Applications & Engineering Value
This black-oxide alloy steel set screw is engineered to address critical challenges in machinery assembly, automotive, and precision equipment. The UNF fine thread and Class 3A fit deliver tight tolerances, reducing the risk of vibration-induced loosening in high-stress applications. The 90° cone point ensures deep penetration into shafts and collars, providing exceptional resistance to rotational forces. Made from high-strength alloy steel and treated with a protective black-oxide finish, it resists rust and wear, making it suitable for harsh operating conditions. Its headless, hex drive design allows for compact installations where standard fasteners cannot be used, ensuring reliable performance in industrial set screw applications demanding precision and durability.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards, including Class 3A thread fit for superior accuracy and UNF fine thread with 1/4"-28 size. It is manufactured in compliance with ASME B18.3 and ASTM F912 specifications, ensuring consistent quality and performance. The product is also RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, confirming it meets strict environmental and safety regulations for industrial use.
